36 results about "Suturing clip" patented technology

A tissue fastening device includes a suture clip holder and a suture cutter. A suture clip can be releasably secured to the suture clip holder, and a suture line or lines can pass through the clip and adjacent the suture cutter. A first movement of a control handle causes the suture clip to be released from the suture clip holder, and a second movement of the control handle causes the suture cutter to cut the suture line or lines. The first movement is different from the second movement. The first movement can be rotational, with the second movement being longitudinal. Alternatively, the first movement can be longitudinal, with the second movement being rotational. The device may include a main body, an inner body, and an outer body.

In accordance with the present invention there is provided a suturing device. The suturing device includes a length of suture that will be delivered to the site of the PFO and placed through the tissue adjacent the opening to close the PFO. As described in greater detail below, the suture is advanced through the tissue surrounding the opening by a pair of needles that penetrate the tissue adjacent to the opening. A knot is then loosely tied with the length of suture and advanced to the site of the PFO. The tails of the suture extending from the knot are then cut and removed. It is also contemplated that a pre-formed or pre-tied knot may be disposed on the device, wherein after deployment of the suture through the tissue adjacent to the PFO and removal of the device a loop of suture having a pre-tied knot will remain, wherein the pre-tied knot may then be tightened to close the PFO. Further still it is contemplated that other means may be utilized to retain the sutures. For example, it is contemplated that a suture clip or other clip like device may be utilized to retain the suture in a position such that the PFO is closed.

Suture clips and suture clip loading, delivery, locking and severing devices in both catheter and endoscopic embodiments are disclosed that permit the delivery and application of suture clips directly in contact with or in close approximation to sutured tissue. The catheter or endoscopic versions incorporate a collet cage with a plurality of flexible collet fingers that captivate a suture clip ring and a suture clip plug for assembly with a suture. An outer sliding sleeve constrains the collet fingers when distally advanced to minimize potential trauma during delivery and assembly of the suture clip in close proximity to the stitched tissue. Proximal retraction of the sliding sleeve coupled with the distal advancement of a pusher against cam surfaces on the inner walls of the collet fingers causes the collet fingers to open. The catheter is designed to hold and assemble the suture clip in a first position and release the suture clip and sever the suture ends proximal to the suture clip in a second position. Single pusher two-step embodiments and double pusher three-step embodiments are disclosed. Suture clip designs with plugs having heads for use with the suture clip delivery catheter are also disclosed. A suture clip loading device for loading suture clip components into the delivery system as well as a threader for threading sutures into the suture clip systems are also disclosed. A method of loading, delivering and deploying suture clips is further disclosed.

A system is disclosed for securing a suture. The system includes a deformable suture clip having a pair of closely spaced panels configured for movement between an open position wherein a suture can pass between the two panels and a closed position wherein the suture can be securely clamped between the two panels. The system further includes a clip applicator having an elongated body defining opposed proximal and distal end portions. The distal end portion of the body includes a mounting fixture having structure for supporting the suture clip in an open position. The clip applicator further includes a mechanism for dislodging the suture clip from the mounting fixture, such that the panels of the clip move to the closed position to securely clamp the suture therebetween.

The invention discloses a pair of operating forceps with suture clip fixing devices. The pair of operating forceps comprises an operating forceps body, wherein the operating forceps body comprises a first clamping arm and a second clamping arm; the first clamping arm is hinged to the second clamping arm to form the operating forceps body; a first suture clip fixing sheet and a second suture clip fixing sheet are arranged on the same side of the operating forceps body; the first suture clip fixing sheet is located at the head part of the operating forceps body; the second suture clip fixing sheet is located at the middle rear part of the operating forceps body; an opening is formed in each of the first suture clip fixing sheet and the second suture clip fixing sheet. The pair of operating forceps with the suture clip fixing devices simplifies the suture knot closing operation and improves the suture knot closing efficiency. In order to facilitate use of the operating forceps with the suture clip fixing devices, the invention further provides a use method of the operating forceps with the suture clip fixing devices.

Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.

A surgical device that includes an outer hollow body and an inner hollow body. The inner hollow body is slidably disposed within said outer hollow body and the inner hollow body includes at least two hollow arms located at the distal end of the inner hollow body. An inflatable member is rotatably attached to each hollow arm of the inner hollow body. At least a pair of suture rings are rotatably coupled to the outer hollow body wherein the suture rings are in parallel to each other and are coupled to each other by a plurality of suture clips.

A suture clip applier for applying a suture around a tubular tissue adjacent to an open lumen. The suture clip applier includes an elongated body having a tissue clinching mechanism at one end of the body. The tissue clinching mechanism comprises two arms that are movable between open and clinched positions. The suture clip applier includes a plurality of deformable suture clips mounted along a longitudinal length of the elongated body, wherein each suture clip is configured to be detachably positioned within an interior of the two arms and to be deformed between open and clinched positions in response to the two arms being moved between the open and clinched positions. The suture clip applier further includes a length of suture comprising a pre-formed adjustable fastening and a loop extending from the pre-formed adjustable fastening, the loop extending between the two arms.

Disclosed herein are annular prosthetic devices, such as annuloplasty rings, that include suture clips integrated into or mounted within an annular frame. The clips can quickly secure to sutures to obviate the need to tied knots in the sutures during implantation. Embodiments comprise an annular frame having an open central region and a plurality of suture clips spaced angularly apart around the frame. Each of the suture clips can comprise two opposing tabs that extend toward each other such that the suture clip forms a gripping region between ends of the tabs and the gripping region is configured to grip a suture inserted through the suture clip between the two tabs. The annular frame and the plurality of suture clips can be formed from a single piece of flat material with the suture clip tabs being formed by laser cutting the piece of flat material, or the suture clips can be movable along a track formed in the annular frame.
